Rioroxy,   I'm really not familiar with the risks of the procedure. Plus, they will vary a bit from person to person, depending on medical history and any other illnesses you may have to deal with.   Your doctor should be able to fully outline any risks.   There are, however, some other issues you need to look at in addition to the risks of the procedure....   1) It is not FDA approved for Migraine prevention. 2) It's not uncommon for the lead wires to slip, rendering the stimulator ineffective. 3) Since it's not FDA approved for Migraine prevention, most insurance companies will not cover it. 4) Some doctors get it approved by insurance companies by fudging the diagnosis. This is illegal and can result in legal action if discovered.   It's not that I want to discourage you, but I think you need to have as much information as possible. Please take the time to read Occipital Nerve Stimulation for Migraine and Headache Prevention - 2008 Update.   You may also want to come by our forum and ask your question to see if you can get more feedback.
